3 Calibration Procedures
54 Keysight E3633A and E3634A Service Guide
Recommended Test Equipment
The test equipment recommended for the performance verification and
adjustment procedures is listed below. If the exact instrument is not available, use
the accuracy requirements shown to select substitute calibration standards. If you
use equipment other than that recommended in Table 3-1, you must recalculate
the measurement uncertainties for the actual equipment used.
